php取值-

php 取值---在线等
echo $images
输出后是
{"image_intro":"images\/f201205281934101426092871.jpg","float_intro":"","image_intro_alt":"","image_intro_caption":"","image_fulltext":"","float_fulltext":"","image_fulltext_alt":"","image_fulltext_caption":""}

不知道有种格式叫json么？

PHP code

$str='{"image_intro":"images\/f201205281934101426092871.jpg","float_intro":"","image_intro_alt":"","image_intro_caption":"","image_fulltext":"","float_fulltext":"","image_fulltext_alt":"","image_fulltext_caption":""}';
$arr=json_decode($str,true);
echo $arr['image_intro'];
